Cons
Con Allows Google to track essentially everything you visit with your browser
Chrome sends usage data to Google.
Con More resource hungry
Con Chrome favors Google's products and tries to satiate Google's data appetite, what hurts the user experience
Con Proprietary
Con Lacks ad-blocking features
Chrome mobile does not support ad-blocking features unlike the Chrome desktop app.
Con Excessive permissions
The permissions required are excessive and intrusive (including record audio) - a few browsers require this, but there are several available that don't
Con SSL Nanny
It is nice that Chrome is strict about SSL warnings, but it would be nice to have an option to connect anyway without needing a secondary browser.
Con Slightly heavier than other options
Chrome uses more system resources than most other browsers, which means it will run slower especially on lower end hardware.
Con Lacks a download manager
Unlike most competitors, Chrome has no built-in download manager.
Con Doesnt support extensions
All extension from chrome web store cannot be used on android version.
Con Owned by a Chinese consortium
Who certainly need to conform with Chinese government requirements to let them infiltrate everything you do online.
Con Trash VPN (Slow and Leaks IP address)
Terrible VPN service. Super slow. It's just a proxy service that leaks your IP address, not a VPN. Not recommended!
Con Cannot select tabs
Unlike in Chrome and Vivaldi, one cannot select multiple tabs to move to another/new window.
Con WebKit/Blink is not customisable or lightweight
Opera is built on WebKit/Blink, which means it shares cons of Chromium: high RAM usage (Not lightweight), lack of customizability.
Con Uneditable default search providers
It can not delete or replace already built-in search services such as Yahoo, Google, DuckDuckGo, and Wikipedia.
Con Proprietary
While Opera is currently available gratis (without monetary charge), it is currently not libre (meaning that it does not allow users to view the source code used to create, to modify that code, or to redistribute modifications) and is therefor neither free nor open-source software.
Con Unable to sync extensions
Imagine having 100 extensions and Opera link cannot sync them, which will be troublesome.
Con No address bar in fullscreen mode
Unlike in Vivaldi.
Con Buggy
Some buggy or confusing behavior with the bookmarks bar and moving tabs, and entire windows turning black after a while.
Con Same security-holes as Chrome
Opera uses the same browser engine as Chrome, meaning it has the same security-holes as Chrome. Chrome is a big target for hackers (being the most popular browser in the world), and a webpage that will hack Chrome will also hack Opera.
Con No reader view
There is a great reader view extension which is available.
Con Built ad-blocker works when it wants
Con Basically a Chrome clone
The latest versions of Opera are basically Chrome clones, so they really don't add anything new.
Con No menu bar
Con The advertisements are terrible
There are too many advertisements in this browser.
Con Extension icons not directly moveable
Con Cannot stop auto update
Con Needs user prompt to install from Chrome web store
Every time you install an extension, you need to say install first from Opera extension list to proceed.
